How do i add images in XNA studio?

Hello,
I tried to find answer of my recent problem through forum, but didn’t have any luck so far.

I am using Torque X 2D platformerdemo .and I add my own images in Torque X. But when I run this in XNA studio, I am getting this error.
SceneLoader.Load – Error loading XML file : ‘data\levels\jin_level_2.txscene’, ContentloadException: ‘Error loading “data\images\test_image”. File not found.’

But when I use starter 2d template, I don’t get any errors with my new images.
I don’t know programming at all. I just wanted to swap images with mine.

I am curious that if I am actually able to import new images in platformerdemo and run this? If so.. Can you tell me what I need to do exactly in XNA Studio?

Thank you for reading this
